Dual Screen Flicker?

I have a new MacBook Pro with a new 20" studio Display attached. I like to run them side by side to give me more desktop space.
After about 1 hour after being connected and ON the MBpro monitor begins to flicker, ghost and go crazy. The external monitor being hooked up has been the only time it does this. I try disconnecting the montitor and plugging back in but it does it again. Only fix is to restart. Any thoughts? Am I doing something wrong?
thanks

Actually, those temperatures are not that high. And it sounds like you are not creating thermal problems since you are allowing air to flow around the MBP. The only thing I would question, since I don't know how big an iTrip box is, maybe that could be acting as an insulator against an important part of the underneath side of the MBP.
A box with still air in it isn't going to be much aid to cooling. In fact, it makes a pretty darn good insulator. It would be better if you could figure out a way to hold the MBP up from it's corners near the area of the rubber feet. That would allow for more surface area of the bottom being exposed to air.

ATI HD 5700 dual screen flicker

     You will see this with boot camp Windows 7 ultimate 64 bit, however when opening a windows media video a slight line/flicker appears then goes away 2 seconds later. I followed every clue and so far have eliminated video card, adapter, wire, and cables. If it is a driver issue both Apple and ATI have not seen it nor has there been a fix for it. 99.9% of Mac Pro users will not see this due to it only happening on a dual screen Windows setup. In OS X Lion it never appears. I truly believe it is software related because I have 2 VGA 19" square generic Acer monitors and when I set the settings to one screen, the problem never appears. Any more input will be appreciated.

The dual monitor setup although new is only VGA in. For some reason the Acer corp can only give
the answer not the reason but dual monitor with lets say 2 other monitors stops this from occuring
so even though these are beautiful screens they will not work properly with setup.
Thank You Acer

Dual screen problems after last updates

Hello everyone,
it was long time since our Arch gave me some problems, but then now I'm fighting furiously with dual screen configuration with new gnome. Let me explain.
I upgraded the home PC that I hadn't update for months, so I updated more or less everything ... kernel, nvidia drivers, gnome, etc..
The PC has always been dual screen (no twin view, without xinerama), two screens (one on a LCD monitor and one on a TV) where I could run separate applications independent.
Now, after the update, when I launch any application in the second screen (the TV) it starts on the first (screen).
Obviously I have't made any changes to xorg.conf before and after the upgrade. I also tried to recreate one with the nvidia-tools but nothing ...
Can you help me? Someone had the same problem?
I post my xorg.conf, I hope that someone has a hint. I can no longer watching movies on TV and it is very annoying!

Writing the post a tried to install fluxbox, and then... all ok. In fluxbox all works fine. I think this is a problem related to the new gnome screen configurer.
I post an image of gnome screen configurer vs nvidia-tools.
Googling around I found that new gnome screen configuration (using xrandr) is not compatible with nvidia drivers. Could be this the source of the problem?
Help please

Hi,
Does your Mac go to the sleep status when you close the cover? If so, the remote session can be terminated due to time out and the time out value may be redesigned in the latest versions.
Thanks.

Perpetual Screen Flicker

I posted a question back in June about my monitors flickering on and off at sporadic intervals. I'm reposting, hoping a fresh set of eyes will see the question and help me out. Thank you.
Without warning, my monitors will take turns turning blue, then black, then coming back on again in a cycle that repeats for as long as 15 minutes. On the black screen, I get a small message that reads "no signal." Just before the monitors 'die' I lose control of my cursor. Any suggestions? Does the info below help? Thanks!

I have a new MacBook Pro 15 inch that I bought the first day they were available. I too have noticed screen flicker. It only occurs on the left side of the screen and is only noticeable at somewhat reduced brightness. I'm trying to decide whether to take it back to Apple for repair or replacement, or whether it should be considered within the working parameters of the screen, as it's not apparent at "normal" brightness, i.e., the brightness most people probably use most of the time. Has anyone consulted Apple about this and got a response?

GTX 780TI GAMING 3G dual screen issue

Hi,
Been searching around but I don't seem to be able to hone in on the right search criteria to find anything.
I have the 780ti running dual screens. I have a nice new 144hz widescreen and I'm running an old Philips 75hz as general purpose screen next to it. I'm keeping hold of the old one at the minute as it works well with my gfs work laptop when she needs a full screen.
When I bring a game up and try and run it on the 144hz screen it tries to swap screen constantly. It flicks back and forwards across both screens at a rapid rate.
I had this working on my very old twin 4870s (you can tell how long I've been out of the game literally) but it occurred to me that I was running a screen off each card. So now I'm wondering if I can run two screens of one 780ti? If that's the case I'll just get another one which I plan to do in the future anyway. But after splashing out 2k on a new machine spending another 500 isn't going to make the gf happy.

It isn't that I want to run across both.
I wanted the game on 1 screen and another screen to put up web pages, voice server etc.
I guess it is the same difference to the card though. I may just be better of with another card and another 144hz screen.
I would've thought running the game windowed and making sure it didn't stray onto the other screen would be possible.

I work on dual screens on a new mac pro but when I do the 4 finger swipe it moves both screens, is there a way to move just the screen that is active?

Multiple desktops and dual screens really aren't meant to work together. Apple came up with this multiple desltops feature and never really thought about users that use a dual monitor setup. So use either multiple desktops OR dual monitors but not both. Also don't try to use any App in Full Screen Mode as that doesn't work with dual screen setups either.

Is it possible to connect my mid 2010 Macbook Pro with my 21.5" iMac 11,2 so that I can work with dual screens?

13" MacBook Pro - Screen Flicker / Windows 7 Bootcamp

I have a 13" MackBook Pro with Retina display that I purchased last December (8 months old). I am running Windows 7 in Bootcamp and the last few months the screen flickers on occasion (becoming more frequent). I launched the Mac OS to ensure I have the latest updates and I believe I do (nothing new to install within the Mac OS). Majority of the time I'm hooked up to an external monitor / lid is closed, but obviously that is a challenge when traveling.
I did do some searches and see other posts around screen flicker issues, but those appear to be on the Mac OS side. What is odd about my scenario is that it only seems to appear on the Windows 7 side. I can't seem to find a fix for this / really would hate to have to reload the machine.

Running Windows 7 Ultimate x64 on my brand new 15" MBP right now.
The only problem I'm having is the USB controller issue that is reported in the following thread:
http://discussions.apple.com/thread.jspa?threadID=2411685&start=30&tstart=0
I ran the Boot Camp assistant, made the partition, rebooted with my 7 DVD, formatted the partition, performed a clean installation, & then installed the drivers from the OSX DVD when Windows booted the first time.
Replaced the NVIDIA drivers with the latest Verde release. 258.96notebook_winvista_win7_64bit_internationalwhql.exe
Everything seems to be running just fine at this point.

What options do I have if I want to set up a dual screen?

I have a Thinkpad T400 with a ATI Radeon HD3470 card. I am running the latest Arch x86_64 with Fluxbox and the 9.4 Catalyst drivers.
What is the easiest solution to set up a dual screen? Is there a way to do this without editing xorg.conf? Not that editing xorg.conf really is a big problem, but I will be moving around a bit and finding the correct settings for each screen would take some work. And I would like to see how far the dual screen development has come on GNU/Linux.
The way I see it the best way would be to have two screens with separate resolutions. Since LCD screens do not handle resolutions other then the native very well. So just stretching the screen makes the slave screen run the same height as the parent screen. Or am I wrong? It is not a problem running stretched if the screens run at the native resolution.
So, xrandr just gives me stretching. And the need of editing xorg.conf.
What about Twinview(just for nVidia) and Xinerama?
Is there other solutions?
SOLUTIONS:
There is arandr and lxrandr, both frontends to xrandr. Requires minimal xorg.conf editing. Only add a virtual line in the screen section. The virtual size does not have to be accurate, it only have to be bigger then the screens together. In my case, I have a 1440x900 primary screen and at most a 1280x1024 secondary screen. So my virtual size would be minimum 2720x1024. This is with the screens side by side. If the screens is one above the other it would be 1440x1924.
The exact size of the monitor is handled by xrandr(arandr or lxrandr). So, there will be no dead zone in the width(side by side solution), if the real height is different on the screen there will be a dead zone in height.
Using arandr or lxrandr means that you manually have to set this up each time the computer is restarted. To automate this, you can use xrandr. First do a
# xrandr
Screen 0: minimum 320 x 200, current 2464 x 900, maximum 2720 x 1024
LCD connected 1440x900+0+0 (normal left inverted right x axis y axis) 304mm x 190mm
1440x900 50.0*+ 60.2
1152x864 60.0 50.0
1280x768 59.9 50.0
1280x720 60.0 50.0
1024x768 60.0 50.0
800x600 60.3 50.0
720x480 60.0 50.0
640x480 60.0 50.0
640x400 59.9 50.0
512x384 60.0 50.0
400x300 60.7 50.0
320x240 60.0 49.9
320x200 60.1 50.0
DFP1 disconnected (normal left inverted right x axis y axis)
CRT1 connected 1024x768+1440+0 (normal left inverted right x axis y axis) 304mm x 228mm
1024x768 60.0*+ 75.0 70.1 60.0*
800x600 72.2 75.0 70.0 60.3 56.2
720x480 60.0
640x480 75.0 72.8 75.0 60.0
640x400 75.1 59.9
512x384 60.0 74.9
400x300 75.0 60.7
320x240 75.6 60.0
320x200 75.5 60.1
to find out where the screens are connected. Mine are LCD and CRT1. Then test with
# xrandr --output CRT1 --right-of LCD
to see if you get a stretched desktop. If this works, just add the last line to your .xinitrc
This solution gives you stretching.

This works, and I get separate resolutions on the monitors. I tried using radeonhd but then the resolution on teh second monitor goes to some crappy values(which I figure are calculated proportionally to the 1280x800 one).

Macbook Pro 13 Early 2011 ocasional screen flicker...

I bought a MBP 13 early 2011 i5 new about 2 weeks ago. Over the last week or so I get an occasional screen flicker. I lasts about a second and that is it. I had a MBP 13 2010 for a year before this one and never experienced this problem with that one. I am running Lion and all the software is up to date. I guess I am wondering if anyone else with this model has experienced this, is normal, or should it be something I should be concerned about. Thanks in advance for any answers on this. Also not related to heating either, temp is running the 40's, and just web browsing.

Call Apple Care. You have 14 days from the date of purchase to return your computer with no questions asked. Otherwise, you have the standard 1 year warranty and 3 years if you purchased Apple Care.
Take FULL advantage of your warranty. Posting on a message board should be done as a last resort and if you are out of warranty or Apple Care has expired.

How do I play a video in full-screen mode on one screen of a dual-screen Windows 7 system without blanking out the other screen?

How do I play a video in full-screen mode on one screen of a dual-screen Windows 7 system without blanking out the other screen? Not losing the other screen would be useful as I would like to, for example, monitor my emails whilst watching a video or to work on a project whilst watching an instructional video.
Note : Resizing a window to fill the screen is not acceptable as it still leaves unsightly borders.

How can I reproduce my screen flicker so they'll believe me?

The intermittent nature of the annoying screen flicker on my Macbook makes it difficult to show a tech that it is a real problem and not some figment of my imagination. Does anybody know of a "sure fire" way of reproducing it? I have been able to recreate the rapid dimming and brightening of my Macbook screen by moving the brightness indicator all the way to the left and then bumping it up one click. This only works sometimes and it only works when I do it by clicking and dragging on the ball on the display screen in system prefs. It doesn't work by using f1 and f2. I made a video of my screen while it was flickering and put the video on the desktop. I'm sending it in as soon as my box arrives on Tuesday. They're also replacing my stained top case. I hope they will look at the video and at least test the inverter and cable to see if they're the problem. Any help with how to encourage them would be greatly appreciated.
macbook Mac OS X (10.4.9)

I am the victim of this problem also. The screen flickering & brightness of the screen suddenly fade to low intensity. The screen flickering happened everytime I use my MacBook.
May MacBook was the initial Jun 2006 version.
I already get those problems (a) sudden shutdown (replace the logic board), (b) palm rest area discoloration (change the bottom case), (c) power adaptor pin contact problem (replace the new one), (d) poor performance of battery life (awaiting confirmation from local Apple support, 180cycle max. charge only 50% of initial capacity) & (e) screen flicker issue (today just send in my MacBook for them to do diagnostic).
I really lost confident with my MacBook.
Should I request a replacement of entire MacBook?
My warranty period will be expired mid of next month & the are asking me to purchase the apple protection plan. But, I claim that the unit is poor in initial build quality & why I should considered the plan. It is unfair to me.
If the MacBook is in good condition then I will consider the plan for support another 2 years (fair), not in this reverse way.
Anybody please guide me how to pursue this matter.
I previously own an iBook G4 & PowerBook G4 TI don't have these problem at all.

Any solution for having daily screen flicker on my 2.13GHz 13" 2011 Macbook Air (running 10.6.8)???

well, the title says it all...I see on the Macbook Pro support threads that this is a continuing issue for that model and people seem frustrated that repeated replacements of motherboard and/or displays are not solving the problem.
I can still use the computer but it is a little disconcerting to have the screen flicker and it seems to be happening almost daily now whereas it used to be more of an occasional thing...
I run Onyx and fix disk permissions and clean out various caches at least once a month...but other than that, I just use the computer for low-intensity tasks of word-processing and web browsing mostly...
just wondering what people have done with this problem?
Thanks,
Eric

I finally found a solution. In about:config, under browser.sessionhistory.max_entries, I changed 5 to 20. End of problem.

I'd like to see next generation of Touchsmart PC with Touchsmart keyboard and dual screen

Where you have a monitor as the display and a seperate keyboard, but the keyboard is another monitor which operates as a keyboard, for example something like this...
This ultimately would mean that the keyboard could be application driven, that is it could be specifically configured anyway that the application requires it. I'd also like to see a dual screen option for touchsmart PC - a screen that is built in and can be slid out from the rear of the monitor to act as dual screen, extended screen...

On my 2012 MBP I can no longer use dual screens/HDMI after upgrading to 10.8.2. I'm using Moshi Thunderbolt adapter

I think you are sailing in uncharted waters with those kind of modifications.
I am only guessing, but if you have not already done so, do a PRAM reset and then trash your FCP preferences.

I've also notice when I start the computer up, it stays on the grey screen longer than it did when I had the original card (512 mb).
My understanding is the Mac is doing a ram/hardware test during the grey screen, if the card you added had additional memory, then it is very likely the test will take longer - but I am no hardware expert.
